The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
kleinanzeigen_get_listing Get full listing detail ~118
Fetch the full detail page of one listing: complete description, price, seller profile, location, images, category path and category-specific attributes. For more than one listing use kleinanzeigen_get_listings_batch instead.
| Name | Type | Req | Description |
|---|---|---|---|
| includeViewCount | boolean | – | Also fetch how many times the ad was viewed. Costs one extra request and increments the seller's counter, exactly as opening the page in a browser would. |
| listing | string | yes | Numeric listing id (e.g. '3487590681') or a full kleinanzeigen ad URL |
No output schema declared.
No examples provided.
kleinanzeigen_get_listings_batch Get full detail for several listings ~101
Fetch full details for several listings in one call — the normal follow-up to a search. Failed ids are reported in `errors` rather than failing the whole call, so a deleted listing does not lose you the rest.
| Name | Type | Req | Description |
|---|---|---|---|
| includeViewCount | boolean | – | Also fetch view counts. Doubles the number of requests this call makes. |
| listings | array | yes | Listing ids or ad URLs, typically from a search. At most 20. |
No output schema declared.
No examples provided.
kleinanzeigen_parse_search_url Explain a Kleinanzeigen search URL ~91
Explain which filters a Kleinanzeigen URL encodes, without scraping it. Returns the filters that map onto kleinanzeigen_search arguments plus any that do not — handy for telling the user what a link actually searches for, or for deciding whether kleinanzeigen_search is enough or kleinanzeigen_search_by_url is required. Makes no network request.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | A kleinanzeigen.de search or category URL |
No output schema declared.
No examples provided.
kleinanzeigen_search Search Kleinanzeigen listings ~238
Search by keyword, location, radius and price. Returns listing summaries — id, title, price, location, teaser and URL. Follow up with kleinanzeigen_get_listings_batch for full descriptions and seller details. Every filter is optional, but a search with neither query nor location returns an arbitrary slice of the site and is rarely useful.
| Name | Type | Req | Description |
|---|---|---|---|
| location | string | – | City name or German postal code, e.g. 'Berlin' or '10115' |
| maxPrice | integer | – | Maximum price in EUR |
| minPrice | integer | – | Minimum price in EUR |
| pages | integer | – | Result pages to fetch, ~25 listings each. Default 1, max 5. |
| publishedAfter | string | – | Only listings published at or after this local ISO 8601 datetime, e.g. '2026-08-01T00:00:00'. Also stops paging once older listings appear. |
| query | string | – | Search terms, e.g. 'ThinkPad T14' or 'Fahrrad 28 Zoll' |
| radiusKm | integer | – | Search radius around `location` in kilometres |
No output schema declared.
No examples provided.
kleinanzeigen_search_by_url Search from a Kleinanzeigen URL ~159
Search using a Kleinanzeigen URL, preserving all of its filters. Use this when the user pastes a Kleinanzeigen search link. Category URLs encode filters that kleinanzeigen_search cannot express — vehicle make, model year, fuel type, room count — and this keeps every one of them. Page numbers are injected automatically.
| Name | Type | Req | Description |
|---|---|---|---|
| pages | integer | – | Result pages to fetch, ~25 listings each. Default 1, max 5. |
| publishedAfter | string | – | Only listings published at or after this local ISO 8601 datetime, e.g. '2026-08-01T00:00:00'. Also stops paging once older listings appear. |
| url | string | yes | A kleinanzeigen.de search or category URL |
